Application filed December 22, 191'?.

To all whom t may concern:

Be it `known that "I, Vieron KoBLnRT' STAUDER, a citizen or' the Republic of Switzerland, residing at Zurich, Huttenstrasse 62, Switzerland, have invented certain new and useful lmprovements in Copy- Holders for Typewriting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being Y had to the accom panying drawing, and to letters or igures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in a copy-holder for typewriting machines.

The object of the invention is to provide a holder of this class, comprising a stirrup supported by the :trame of the typewriting machine and a plate for carrying the copy, the stirrup and the plate being adapted to be brought near to the frame of the machine, when the holder is not used, so that itis then not standing in the way.

This invention will now be more` particularly described with reference to the accompanying drawing, which illustrates a constructional example of the invention.

In this drawing;

Figure 1 is a front elevation of a typewriting machine provided with the novel copy-holder Fig. 2 is a corresponding side view;

Fig. 3 is also a side view, illustrating a part of the holder-plate in another position.

Fig. 4 is a front view on an enlarged scale of the copy-holder.

Fig. 5 is a cross-section on'the line V-V- of Fig. 4 and Figs. 6--8 illustrate `on an enlarged scale several details.

Figs. 9--10 illustrate a modification of a detail.

To the rear braces of the typewriting machine 1 is secured a stirrup 4 by means of clamping bearings 2, 3. The stirrup 4 consists of a bar having a circular crossssection. Each clamping bearing 2, 8 comprises two flat members 2 and 3 connected by means of screws 5. rlhe ends of the stirrup 4 are connected by means of a rod 6 having also a circular cross-section. lThe rod 6 has pins resting` in the slotted end of' the stirrup 4. The slotted ends of the stirrup 4 can be pressed together by means of screws 7, the

rod 6 being then clamped in said slotted ends (Fig. 4). To the rod 6 is fixed by means of short, bent arms 10 a plate consisting of two halves 8 and 9. The arms 10 carrying the plate piece 9 are rigidly connected to the rod 6, while the arms carrying the plate halt' 8 are loose on the rod 6, so that the plate half 8 can be rotated about the rod 6. To the latter is fixed a disk 11 provided with a recess or slot 12. The plate half 8 is provided with a pawl 14 acted upon by a spring 13.. TWhen the'two plate halves 8, 9 are lying in one plane, the pawl 14 engages into the recess 12 of thev disk 11 securing thereby the two parts 8, 9 in the proper position with regard to each other.

Each plate half 8 and 9 respectively, is provided with a wire stirrup 15. The ends of the stirrups 15 are pivotally connected to the rear-side of the parts 8, 9. These stirrups 15 are bent in the manner illustrated in Fig. 5 over the upper edge of the plate part 8 andthe lower edge of the plate part 9 respectively, the bridge pieces 15 of the stir rups resting on the front side of the plate halves 8, 9. Springs 16 press the bridge pieces 15 against the two plate halves 8, 9. Fach plate half 8 and 9 respectively, is provided on one side with a toothed rack 17. When the two halves 8, 9 are lying in one Patented Feb. 10, 1920.

plane, the two racks 17 form one continuous track.

18 (Figs. 7 and 8) denotes ak slide surrounding a part of one of the toothed racks 17 and. the edge of that plate half on which is mounted said rack 17. The slide 18 carries a toothed wheel 19 rigidly connected to a small hand wheel 20. rlihe toothed ywheel 19 engages the rack 17 and a spring 21 arranged between the hand wheel 20 and the slide 18 is adapted to exert a brake action upon wheel 19. The slide 18 is provided with a cover-like member 22 acted upon by a spring 21a. To the member 22 is xed an index rod 23 extending across the whole width of the plate 8, 9. n

When the copy to be put on the holder is approximately as long as the plate 8, 9, the two halves of the latter are adjusted in such a manner, that they come to lie in one plane. rlhereupon the two plate vhalves 8, 9 are fixed in the proper manner. vThe copy isv put be neath the index rod 23 on the plate 8, 9, the upper and'lower ends of said copy being clamped to the plate by means of the bridge pieces 15 of the wire stirrups 15. (Figs.

1, 2 and 5). The typewriter can now move the plate 8, 9 supporting the copy into any inclined position and he can also bring the copy within the range of movement permitted by the stirrup 4, at any distance from him. The hereinbefore described holder combines therefore with the advantage, that the plate S, 9 is adapted to be moved above the typewriting machine, the further advantage, that the plate 8, 9 can also be brought on the desired level with regard to the eyes and that the position of said plate can be adapted to the visive faculty of the writer. An important advantage consists also in that the stirrup 4 supported in the frame of the typewriting machine is connected in the middle of the plate 8, 9 to the latter, so that any vibrations of the plate, and therefore of the copy, are diminished during the typewriting. A vibrating of the copy-holder would occur when the stirrup 4 would be connected to the upper or lower end of the plate 8, 9, the latter forming in this case a long lever-arm on the stirrup 4.

The rod 23 is for indexing the line, which has just to be copied. The rod 23 is kept in the proper position by the spring 21 exerting a brake action upon the toothed wheel 19 engaging into the toothed rack 17. In order to impart a feed movement to the indexing rod 23, the small hand wheel 20 has to be rotated. The toothed wheel '1.9 is then" moved along the toothed rack 17 causing the rod 23 to move relatively to the plate 8, 9. When the copy is higher than the plate 8, 9, the parts of the copy projecting beyond the upper and lower edges of the plate may be inserted into the wire-stirrups 15 (Fig. 5). When, on the other hand, the copy is only small and has, for instance, the size of a post-card, the pawl 14 is moved out of the recess 12 of the disk 11 and the plate half 8 is turned around, so that it comes to lie behind the plate half 9 (Fig. 3). The width of the wire stirrup 15 of the plate half 9 exceeds to such an amount the width of the stirrup 15 of the plate half 8, that the stirrup 15 of the plate half 8 is clamped between the ends of stirrup 15 of the plate half 9 when the two halves 8, 9 are moved toward each other, the two plate-halves 8, 9 being thus secured in their proper position when they are parallel to each other. The copy is put in this case on the plate half 9 and secured in the proper position by means of the wire stirrup provided on said part 9.

When the copy-holder has not to be used, it may be brought into the position illustrated in Fig. 2 in point and dash lines, in which position the holder is not standing in the way. In this position of the holder the machine can be covered in the usual manner with an oil-cloth or the like and it is also not in the way when the machine has to be carried about.

ln order to facilitate the putting of the copy on the plate 8, 9 and the removal of -such a copy, the rod 23 has to be lifted.

rlhis can be eected in a very simple manner by lifting the member 22.

rlhe stirrup 4 projects on both sides of the typewriting machine to such an amount beyond the latter, that it does not prevent in any position of the carriage of the machine a movement of the sheet wound around the machine platen.

The clamping action in the bearings 2 and 3 and in the ends of the stirrup 4 can be adjusted in such a manner by means of the screws 5 4and 7 respectively, that said action is great enough to fiX the stirrup 4 carrying the plate 8, 9 and the latter in any desired position.

As shown in Figs. 9 and 10, the toothed rack 17 can also be dispensed with. In this embodiment the toothed wheel 19 is replaced by a friction roller 24 acted upon by a spring 25, which is adapted to press said roller 24 against the plate S, 9.
